'lhe prin'cipal bj.ect of my invention is a new and improved meehanismf01' oscillating an electxic fan. Ano'ther 0bjeot of my invention is fioprovide an oscillatin-g mechanism c0mprising a yield'mg ele- 1nent sothat the fa-nmay not. become damaged. i'f it 1S' bloeked in anypartieu'lar position. A furher object 0f my invention is t0 provide anoscillating fan that may .be quickly adjustecl so that; the meanposntion shall be in any desirecl horizontal direction. Still anotherobjeet of my invention is to provide oscillating meehanism such that thefan may be tiltecl at any desix'able vertical angle While the ax'1s ofthe oscillation remains vert'1eal. All these objectS and various otherswill be made clearin the fol-lowing specification and; olai-xns, takenin counection witl1 ehe amompa-nying drawings.

In alinement with t-hissl1aft 28 is the serew stud 29, which may bemanipulated by means of tl1e' winged laeaxl 30. The shaft 28 and thestud 29 are sup-ported 011 the ends 0f tl'1e respective arms 20 andconstitute a horizontal axis ab0nt Which the motor 22 may be tilted in aVertical plane.

One arm 20 carries a bevelecl gea1 wl1eel 31 thatis engaged by the gear27. The shaft f0r tl1is gear wheel 1s journaled in tl1e sleeve 32 andearries a crank disk 33 at its lower end. The stud34 in the disk 33constitutes a wrist pin which engages 0ne end 0f the link er con-necting10d 35. Theother end 0t' the link 35 is engaged by the stud 38, attaehedto the collar 36 that loosely surohe l1ead 17 and the member 19. Thiscollan 36 has a por-v tion 0f one side cut away, -as inclicated. by thereferenee nu'meral 37, and the Stud 38 is in this cutaWay portion. Thecollar 36 has a deep noteh 39 ab one side,;in whioh lies a dog 40 with adownwardly projecting tongue 41 carrying -two teeth41 that engagethenotches 42 around t-he periphery of the a soc'ketz- 43 in Whieh lies ae0'11 spring 45. The screw 44, actin-g upon the spring 45, holds the dogin the notch 39 and holds the teth in enga-gement with.t he notches 42.As themotor 22 revolvesancl drives the fan 21, a .slow rotation is giventln0ugh the ge;aring deseribed to tl1e cr'ank clisl 33.
